Problem 2: According to the Loselt! Mobile App, you will get 140 calories from a serving of vanilla yogurt. Consumer Reports tested 14 brands of vanilla yogurt and found that the average calories per serving was 158 calories with a standard deviation of 44.7 calories, with a distribution that was approximately unimodal and symmetric. A. Create and interpret a 95% confidence interval for the average calorie content of vanilla yogurt. (State your conditions for inference.) B. Based on your confidence interval, is there evidence that the Consumer Reports test is different than what Loselt! Mobile App claims? Explain.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
